FLEXIBLE HINGE TOE IMPLANT WITH SWANSON FLEXIBLE HINGE GROMMET Bone edges are carefully smoothened. A trial fit is made with the appropriate color coded sizer. The implant should fit well into the canal so that the transverse midsection of the implant abuts against the bone ends. The end of the implant stems must not impinge against the end of the intramedullary canals. When the lateral metatarsal heads are not resected, it is important to retain a portion of the first metatarsal head to avoid shifting of the weight bearing to the second metatarsal head. In these cases, to obtain the...
